1-5 System Configuration
The Ladder Monitor can be started using the Special Screen Tab Page in the PT System
Menu when the system is configured with an NS-series PT connected to the host PLC by
RS-232C, Ethernet, or Controller Link communications. For pre-version-1 and version-1
NS-series PTs, however, a Memory Card containing the Ladder Monitor application must
be mounted at the back of the PT, as shown in the following diagram.
I/O comments can be read from a symbol table in the PLC. There is no need to copy I/O
comment files to a Memory Card when a symbol table is downloaded to a connected
PLC.

Version-2 NS-series PTs
For version-2 NS-series PTs (except for the NS5-V2) with system version 6.6 or higher,
the Ladder Monitor is built into the system program and thus a Memory Card is not
required except for the following operations:
Creating hard copies of screens (i.e., screen captures).
Displaying I/O comment files that were created using the I/O Comment Extracting Tool.
